| Question | Answer |
|---|---|
| does length effect the pendulum? | yes |
| the time for one cycle | period |
| the pilled up energy | sound barrier |
| when the listener can hear a boom | sonic boom |
| how do u calculate the speed of a wave | by multiplying the wavelength by the frequency |
| when the crest of 1 wave overlaps the trough of another | destructive interference |
| a change in frequancy due to the motion of the source of wave | the doppler effect |
| this wave occurs when a wave souce moves faster than the wave it produces | bow wave |
| this wave occurs when an object moves faster than the speed of sound | shock wave |
| a wiggle in time | vibration |
| one complete back and forth swing | cycle |
| a pictorial representation of a wave formed by swinging a pendulum or bouncing a spring | sine curve |
| when the crest overlaps a crest | constructive interference |
| sound waves are these kind of waves | longitudinal |
| the distance from the top of one crest to the top of the next one | wavelength |
| lower waves have less of this | energy |
| back and forth vibrating motion | simple harmonic motion |
| the maximum displacement from equilibrium | amplitude |
| the high point on a wave | crests |
| the unit of frequency | hertz |
| the low points on a wave | troughs |
| waves per second | hertz |
| a 3 dimensional cone shape | shock wave |
| forns when only half a wavelength or a multiple of half a wavelength fits exactly into the length of the vibrating medium | standing wavee |
| occurs when waves from different sources arrive at the same point-at the same time | interference patterns |
| nodes | destructive |
| antinods | constructive |
| standing waves have different | frequencies |
| these waves are found in strings of musical instruments | standing waves |
| sound and light waves also produce | the doppler effect |
| does an ambulance coming towards you have a high or low pitched sound | high |
| light source that moves towards you that has a higher frequency | blue shift |
| light source moving away from you has a lower frequency | red shift |
| this wave overlaps at the edges occurs only when the source travels faster than the wave speed | bow waves |
